iphone lagging?
for context i like to listen to music while i tan, and i usually put my phone under a towel to reduce sun exposure. sometimes it will tell me my phone is too hot so i will bring it inside to cool down, and then everything is fine. yesterday i was tanning, my phone didn’t overheat but it was still a little hot but didn’t think anything. i noticed my phone was lagging the rest of the night and thought it just needed to charge and be left alone for the night. i woke up and it was still lagging, and is still lagging as i type this. what could be happening? i do have an iphone 13 but ive never had any problems up until yesterday.
